The CPS SCH100-125KTL family consists of three-phase string inverters from CHINT Power Systems. It covers the SCH100KTL-DO/US-600, SCH125KTL-DO/US-600 and SCH100KTL-DO/US-480 models. The rated AC output is 100 kW or 125 kW, depending on the model. The 600 V models output 600 Vac and the 480 V model outputs 480 Vac. All models accept up to 1500 VDC on the DC input and a maximum PV input current of 275 A. Through the FlexOM gateway card, the inverter communicates over standard Modbus RS485, SunSpec Modbus and HTTPS/XML for third-party monitoring and control. Remote diagnostics and firmware upgrades are listed as standard with the CPS Flex Gateway. The CommErr alarm means internal communication failed, which can be caused by poorly seated internal communication terminal blocks. The ExtFanErr alarm points to a blocked fan, a fan at the end of its service life, or a poor fan socket contact.
